不同产地当归中阿魏酸的含量比较

Comparison of the contents of ferulic acid in Angelica sinensis Oliv.from different regions

目的 比较不同产地当归中阿魏酸的含量。方法 以高效液相色谱法测定 2 1个产地的当归的阿魏酸含量。结果 2 1个不同产地当归样品中阿魏酸的含量在 0 .2 4 3%～ 1.0 2 6 %之间。非道地产区的甘肃陇西、云南丽江产当归阿魏酸含量最高 ;岷县清水乡产当归的含量最低 ;而传统的道地产区甘肃岷县各乡所产当归的该成分含量只处于所有样品的中等水平。结论因此 ,以阿魏酸为指标并不能很好地支持道地药材理论 。

OBJECTIVE - To compare the contents of ferulic acid in Angelica sinensis Oliv. collected from 21 different regions. METHODS - The content of ferulic acid was determined by RP-HPLC. RESULTS - The contents of ferulic acid in all the samples changed from 0.243% to 1.026%. The contents of ferulic acid in Angelica sinensis Oliv. from non-genuine herbs in Longxi, Gansu and Yunnan Lijiang were the highest. The lowest contents were found in the herbs from Qingshui and Minxian. CONCLUSION - The contents of ferulic acid from genuine herbs were only on the middle level.
